81 mm (Split Ring Ans Flake)
These increments charges are fired by all 81mm mortars. There are kinds of double-base propellants containing NC, NG, plasticizer and stabilizer. Packing Split Ring It is charged in Viscose rayon ring shape bag, and each set is packed inside PE bags. Packing flake: It is charged in horseshoe celluloid and each set is packed inside PE bags. Storage: Should be stored in -10 up to +30°C Shelf life: 15 years (min)
